Which mill is good choice for purchasing EN S420ML steel plate in China

Based on the advantages of EN S420ML steel plate steel resources in domestic market and good reputation, combining with the huge international market demand for steel products, our company started the international business in 2010 and successfully being approved and certified by ISO9001:2008, the Registration number is 626014Q11531R0S. With the quality steel EN S420ML steel plate products and professional service, our company was award the international acclaim from infrastructure, shipbuilding, petroleum industry etc., and gradually grow into a bright star in the steel export industry .

Compared with ordinary steel, structural steel has the following differences. First, the strength of structural steel is high, and its bearing capacity is far greater than that of ordinary steel. Second, the structural steel has low impurity and carbon content, uniform material and good performance. Third, structural steel has light weight and is suitable for building various frames. Fourth, it is convenient to build structural steel, which is conducive to construction efficiency and reduces construction time. In some construction fields, structural steel must be used. Where can we find EN S420ML steel plate, structural steel suppliers?

There are many advantages of EN S420ML steel plate, pickling coils. The surface of pickling coil is smooth, and the outside is very beautiful. From the appearance, we can see how the manufacturer's technology is, and it is convenient to use pickling coils in engineering. In addition, the cost can be reduced by using pickling coil instead of cold rolled sheet. The corrosion resistance of pickling coil is better than ordinary steel plate, and its service life is also very long.

The blanking of the structural steel plate is first to find 90 degrees, and then use a tape measure and a powder line to draw the cutting range. According to the thickness of the carbon steel plate plus the cutting allowance, drilling is required. For the deep processing of EN S420ML steel plate structural steel sections or profiles: First use a square ruler or a curved ruler to find 90 degrees, and then use a square ruler or a ruler to cut the line and add the cutting margin to the hole.

Chemical composition of 65Mn steel: C 0.62-0.70, Si 0.17-0.37, Mn 0.90-1.20, Cr ≤ 0.25, Ni ≤ 0.30, Cu ≤ 0.25. 65Mn steel mechanical properties: tensile strength: ≥735 Mpa, yield strength: ≥430 Mpa, elongation after fracture: ≥9%, reduction of area: 30%, impact absorbed energy: no impact. EN S420ML steel plate, 65Mn steel has high strength, high hardenability, less decarburization tendency, overheat sensitivity, easy to produce quenching cracks and temper brittleness. 65Mn steel is used for making various flat and round springs, leaf springs, spring rings, valve springs, steel wire cold coil springs, clutch springs of light trucks and cars.

The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.
